Abstract (en)

[origin: EP0260328A1] Injection moulding machine, in which injection is controlled using an NC controlled servo motor (M), comprises a pressure detector (26,27,60) which detects pressure imposed on resin in the mould, a comparator (70) which compares a set pressure and the pressure detector's output and emits an output signal when the latter is higher, a dwell controller (30) which starts dwell control in response to output of the comparator or a timer, and a follow-up means (30) which, when dwell control has ended, refers to a servo motor drive circuit (50) error register (51) and forcibly completes pulse distribution if requisite pulses have not been supplied.
